मैं Ubuntu 10.04 का उपयोग कर रहा हूं। मुझे एक .3gp फ़ाइल को PCM WAV में बदलने की आवश्यकता है। मैं उस के लिए ffmpeg का उपयोग कर रहा हूँ।
जब इसे रिपॉजिटरी से इंस्टॉल किया जाता है, तो aptitude install ffmpegइसका कुछ मूल संस्करण इंस्टॉल करके इसका उपयोग किया जाता है और मुझे इसकी आवश्यकता नहीं होती है।
मैंने नवीनतम यास्मीन ver.1.1.0 और नवीनतम x264 - 0.125.2208 स्थापित किया है। उसके बाद मैं से Git का उपयोग कर ffmpeg मिला आधिकारिक होमपेज के साथ git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg।
मैंने स्वयं का उपयोग करके ffmpeg को कॉन्फ़िगर करने का प्रयास किया:
./configure --enable-gpl --enable-version3 --enable-postproc
--enable-nonfree --enable-swscale --enable-pthreads --enable-libmp3lame
--enable-libx264 --enable-libopencore-amrnb --enable-libopencore-amrwb
तब: time make && make install।
इस समय तक सब कुछ ठीक था। के साथ रूपांतरण के बाद
ffmpeg -i audiotest.3gp -f s16le -ar 8000 -acodec pcm_s16le audio.wav
मैं इस PCM .wav फ़ाइल (ffmpeg -i audio.wav) के बारे में जानकारी जाँचना चाहता था और मुझे यह त्रुटि मिली:
~# ffmpeg -i audio.wav
